In many cases pateints dont use a meter for testing its bulky and often they forget to test al together.
there was an article at AMA site on using color change strips and urine test strips instead of meters for keeping tabs.
I found Betacheck has a complete idea on this traditional check system!

It takes one minute. The strips can be cut in half so you can manage twice the amount of testing. Apply a small drop of blood, let it sit for 30 second, then wipe and sit for 30 seconds more. then read the color!
Now this is cool for traveling wihtout the need for meter read errors.
it seems like something that woudl be hand for airline travel too where your restricted on meters............
